Actually, I rather like Gnome as evident in the version that came with Gnome Ubuntu 13.04, but that is besides the point. RHEL 7 will ship with a Gnome desktop on desktop clients, and whatever Red Hat release will be cloned into CentOS, Scientific Linux and Springfield Linux. That, I gather, in total, is rather a large number of screens. The users of those screens in various organisations will not be able to install a different DE as they (may) not have admin rights and (may) not have access to repositories with alternative DEs available. Red Hat have already suggested that they will be releasing the RHEL 7 desktop with gnome classic as the default to minimise training costs. If anyone here knows of a RHEL type managed system with a large number of screens, it would be interesting to see how RHEL 7 is accepted over the next few years (of course, they may decide not to upgrade until RHEL6 is EoL).
